Our most popular series of wiring!

Keeping your vehicle factory-original?
If you want to rewire your vehicle to the way it left the factory, whether your vehicle will be a "driver" or judged at a car show, the choice is simple.  Our Original Design Series™ wiring is the choice for you.

Our Original Design Series™ wiring harnesses are made to exact factory specifications using the original factory blueprints. They are "correct" in every way. These wiring harnesses are necessary for: owners who want an authentically restored, show-quality vehicle, those who want to replace their old original wiring, or those who want to add original, factory-installed options. These harnesses are completely assembled, "plug & play" - ready to install.  You will not have to cut any wires, crimp any terminals, or make any modifications to the harnesses.

You can also purchase additional wiring harnesses if your vehicle had factory-installed (not dealer installed or aftermarket) options.  For example: air conditioning, power windows, rear window defogger, power top, etc.).  These additional harnesses will plug directly into the main harnesses as they did at the factory.

With our Original Design Series™ wiring, you can either rewire the vehicle one harness at a time, rewire a specific area of the vehicle (for example, the engine compartment), or what we recommend, completely rewire the vehicle bumper-to-bumper by purchasing all the harnesses at one time; and saving 10% off your entire purchase!

Keeping your vehicle factory-original (with specific modifications)?
If you want to retain most of your vehicles originality but want to make some update modifications, specifically:
■ Are you moving the alternator to the opposite side?
■ Are you replacing an externally regulated alternator/generator with an updated internally
   regulated alternator?
■ Are you adding GM HEI?

If you've answered yes to any of these questions, we may have an easy solution.  Due to the popularity of these updates, for some makes/model cars, we offer a modified wiring harness, conversion wiring harness, or conversion device to accommodate these updates.

In this situation, we recommend that you purchase our Original Design Series™ wiring and the appropriate conversion product(s).  Please consult our online catalog to check availability on your specific make & model vehicle, or call our technical support department for more information.

Keeping your vehicle factory-original (with slight modifications)?
If you want to retain most of your vehicles originality but want to make more modifications than those listed above, you can either start with all-original wiring by choosing Original Design Series™ wiring and making the necessary modifications yourself, or , choosing the Custom Update Series™ wiring (as described below).

For faster, easier installation, we recommend staring with an electrically sound foundation by choosing the Original Design Series™ wiring, rewire the entire vehicle as-original, then making the necessary modification yourself. Keep in mind that many of the added aftermarket devices you purchase (like gauges, lighting, electric fans, etc.) come with their own wiring.  All you need to do is to tap into your wiring harness to add those devices.

GM Wiring Harness Systems for "Customized" Vehicles

Building a primarily custom or full-custom vehicle?
If you've customized, or plan to customize your vehicle, we offer our Custom Update Series™ wiring system.

But the question to be addressed is, What is meant by "Customize"?

Ultimately, that will be for you to decide.  But here are some guidelines:
Do you have one of the vehicles listed below?
         1953-62 Corvette
         1967-73 Camaro
         1964-72 Chevelle or El Camino
         1959-64 Impala (Full-Size)
         1947-1972 Chevy or GMC Truck
         1955-57 Chevy Passenger Car, Wagon or Nomad
         1964-73 GTO or Firebird
         1962-72 Nova
         1970-72 Monte Carlo
         1964-70 Ford Mustang
         1953-56 Ford Truck

Do you want the flexibility to route your wiring the way you want?
Do you want to hide your wiring, and need longer-than-factory wire to do so?
Do you want original equipment style connectors and terminals for aftermarket gauge
   or instrument panels?
Do you want an updated fuse block with room to add more circuits to connect other
Do you want to save money by cutting most of the wire to the length you need,
   crimping most of the terminals yourself, and taping the harness to suit your needs?
   (Detailed instructions included.  Harness tape and convoluted tubing not included.)

If you've answered YES to the above questions, than our Custom Update Series™ wiring system is an option for you.  But please read the information below to be certain.

The Custom Update Series™ Wiring Systems are designed for upgraded/modified vehicles. 
Consequently, they do:
■ not support a point-type ignition system. (But can be used with an HEI or sold-state ignition system.)
■ not include a resistance wire so they will not support a point-type ignition system.
■ not support ANY ammeters. (But they will support voltmeters.)
■ not support a stock voltage regulator or SE series alternator.  (But they will support SI series internally regulated alternators and 1-wire alternators.)

Our Custom Update Series™ wiring systems are designed with the foresight and engineering to bring your electrical system up to date. They allow you the freedom and flexibility to wire your vehicle the way you want. This system is not a generic wiring harness, but is designed specifically for the GM models shown below. These wiring systems are popular with owners of fully-customized, pro-street and retro-rod/modernized vehicles.

The Custom Update Series™ wiring system will rewire the entire vehicle (head light -to- tail light).  But bear in mind that our Custom Update Series™ wiring system is for a base-model vehicle and (unless noted) does not include the wiring for options like factory air conditioning, power windows, power top, rear defogger, cruise control, etc.  The wiring for those devices should be included by the manufacturer of those options, should you decide to add them.

Detailed instructions are included all our Custom Update Series™ wiring systems.
